Question

QUESTION 1 A new kind of pet is in the market has fur color that is regulated by 5 unlinked genes F, G, H, I and J which are enzymes. Each enzyme converts one compound into a different one. Allele F converts the colorless 1 compound into a red compound. Allele G converts colorless 2 into yellow. Allele H converts colorless 1 into colorless 2. I converts colorless 2 to red. Allele J converts red into yellow. When both the red and yellow compounds are produced animals are orange. What pet fur color does an animal with an FF gg HH II JJ genotype results in pathway 1 and pathway 2?_ _ _and Pathway 1 red Colorless 1 Colorless 2 yellow Н Pathway 2 red Colorless 1 Colorless 2 G yellow A. yellow and yellow B. yellow and red C. red and red D. orange and red

Answer 1

The correct option is B i,e yellow and red.

Pathway 1:

According to pathway 1 colourless 1 is converted into red because F allele is present in the organism. This red is then converted into yellow by J allele present in the organism. So according to pathway 1 organism will be yellow in colour.

Pathway 2:

According to pathway 2 colourless 1 is converted into colourless 2 by H allele. Colourless 2 can be converted into red and yellow by alleles I and G. As organism contains only I allele which produces red colour, so organism will be red in colour.
